Automatic Steel UV Aging Test Chamber , Standard UVA Accelerated Weathering Tester
Product description:
UV Aging Test Chamber Optimal fluorescent UV lamps using analog section sunlight UV spectrum, combined with temperature control, and other apparatus for the wet material to cause discoloration analogy, brightness, strength decreases, cracking, flaking, dusting, oxidation and other damage sunlight (UV) , At the same time through the synergies between ultraviolet light and moisture makes the material a single light resistance or a single ability to weaken or failure, which is widely used to evaluate the weather resistance of materials
Application industry (not limited to the following):
1. Paint ink paint, resin, plastic
2. Printing and packaging, aluminum, adhesives
3. Motorcycle industry, cosmetics,
4. Metal, electronics, electroplating, medicine
5. Textile,fabric,rubber,and so on.
Applications function:
1.Simulate the sun, rain spray and condensation resulting damage to
test the materials by exposure to sunlight with moisture and
temperature.
2.To get the results of damage after several days or weeks which is
equal to expose to outside for a few months. The damages include
fading, discoloration, brightness down, powder, crack, blur,
brittle, strength decreases and oxidation.
3.Provide reference with testing data for improvement of existing
materials, or to assess the impact of changes in product durability
and other aspects.
Test standard(inculding but not limited to... ):
Compliance with ASTM G154, GB/T5170.9 standards,etc.

Chamber Structure
The inner bladder of the chamber is made of imported high-class
stainless steel plate while the outer bladder is made of SUS 304
steel plate.
The heating mode adopts inner bladder trough type heating with its rapid temperature rise and even temperature distribution.
Control System:
Adopts black aluminum plate to connect temperature sensor and
adopts black board temperature meter to control heating so as to
ensure more stable temperature.
The radiometer probe is fixed so as to avoid the frequent
installation and disassembly.
The radiation quantity adopts the special UV irradiatometer with
high-precision display and measurement.
The radiation intensity is not more than 50W/m2.
The illumination and condensation can be controlled independently
or alternating and circularly.
Test Specimen Mounting:
The standard test specimen holder accommodates 2 panels 75×150mm. The test panels are actual the side wall of the chamber. To properly seal the chamber, it is important to have every panel holder filled with specimens or blank panels and to have panel holders in place.
